STEEL Series 6.0kW Sauna Heater
The HUUM STEEL 6.0kW sauna heater is an electric sauna heater with a large rock capacity, yet remarkably small safety distances, making it ideal for saunas with limited spaces. The STEEL 6.0kW sauna heater is designed for sauna spaces up to 353 cubic feet (CF).
Enjoy a superior sauna experience while adding beauty to your home sauna!
STEEL electric sauna heater from HUUM is a slim, space-efficient unit with remarkably small safety distances, making it perfect for saunas with limited space. Thanks to its well-optimized structure the safety distances from the walls are brought down to just 2" (5 cm) with smaller models and to 4" (10 cm) with larger models. STEEL heater also comes in an even slimmer 3.5 kW wall-mounted model which is particularly suitable for very small sauna rooms.
Because of its intelligent design, the STEEL has a much higher stone capacity that other heaters, providing a more consistent, high heat, better steam capability, and an elevated bathing experience.
HUUM UKU sauna controls (sold separately) are available in a variety of finishes to suit your taste, and include W-Fi options so you can conveniently control your sauna from your smartphone!
